Dot plots are used to represent data using dots
The true statements about the dataset are:
- The range of the number line should be 0 to 7 to represent the frequency.
- Four families said they ate out twice the previous week.
- One family said they ate out 5 times the previous week
The dataset is given as:
4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1
Rearrange in ascending order
0, 0, 1, 1, 2, 2, 2, 2, 4, 4, 5, 6
Represent as a frequency table
Data Frequency
0 2
1 2
2 4
3 0
4 2
5 1
6 1
See attachment for the dot plot
From the attachment, we can see that:
- 4 has a frequency of 2
- 5 has a frequency of 1
Also, the range on the dot plot can be 0 to 7, because it covers the given dataset
Hence, the true statements are: (a), (b) and (c)

Answer:
The correct option is 3.
Step-by-step explanation:
It is given that the quantities of blue and green paints used for each mix and connected them using a line segment, as shown in the graph below:
The line have two end points A(1,2) and B(9,14).
Domain is the set of inputs. In a graph all the values of x for which the graph is defined, are domain of the function.
The line is defined from x=1 to x=9. So, the domain of the function lies between 1 to 9 (inclusive).
Therefore, option 3 is correct.
